MACHINE FOR MAKING BAGS OF PAPER. v

Specification of Letters Patent No. 9,355, dated October 26, 1852.

To all whom it may concern:

Be it known that I, FRANCIS WOLLE, of Bethlehem, in the county ofNorthampton and State of Pennsylvania, have invented a new and usefulMachine for Making Bags of Paper orother Material; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming partof this specification, in which Figures 1 and 2 are elevations ofopposite sides of the machine. Fig. 3, is a longitudinal verticalsection of the same looking in the same direction as in Fig. 1. Fig. 4,'is a transverse vertical section of the same in the line aw of Figs. 1,2, and 3, looking in the direction of the arrow 20. Fig. 5, is avertical section of the parts which lap and paste the side of the bags,taken in the same .plane as Fig. 3, but looking in the oppositedirection. Fig. 6, is a top view of the parts which measure out thepaper, out it from the roll, out out a piece to leave the bottom lap,and fold it. Fig. 7, represents one of the pasters detached from themachine. Fig. 8, shows the shape of the piece of paper after it is cutout, and Fig. 9, exhibits the same folded.

Similar letters of reference indicate corresponding parts in each of theseveral figures.

This invention consists in certain devices by the combined operation ofwhich pieces of paper of suitable length are given out from a roll ofthe required width, cut off from the roll and otherwise suitably cut tothe required shape, folded, their edges pasted and lapped, and formedinto con'i plete and perfect bags which when dried will be ready foruse.

To enable others to make and use my invention I will proceed to describethe several parts in detail, and the manner in which their operation isconducted.

The working parts are all supported by a framing A, A, of suitablematerials form, strength, and dimensions, all their movements beingderived from the main shaft B, to which a continuous rotary motion isgiven by any suitable means in the direction of the arrow 30. The paperfrom which the bags are made which is represented in red color in thedrawing, is in roll of a width suited to the depth of the bags, and iswound upon a reel C, whose axis a turns freely in suitable hearings inthe upper part of the framing near one end of the machine. One end isled between the two taking off cylinders D, D, which receive anintermittent rotary motion, being caused to make one revolution and thenstop for a short time previous to making their next revolution. Theserollers are of such diameter that one revolution will unwind from thereel a suflicient length of the roll of paper to make both sides piecefor the lap of the joint; they receive their motion (see Fig. 2) throughan oval cog wheel E, which is fast on the axis Z), of D, and is drivenby an eccentric wheel F, of segmental form on a shaft 0, which receivesmotion through an endless chain Gr, passing over a chain wheel I-I, fastupon it, and around a chain wheel I, of correspond ing size on thedriving shaft. The chain gives a continuous motion to the shaft 0, butthe wheel F having no teeth on the part forming the chord of the segmentceases to give motion to E, while that part of its circumference ispassing, thus the cylinders D, D, stop their revolution while 'thete'ethof E, and F, are out of gear, but theteeth of F, being equal in numberto those of E, always give it one complete revolution between thestoppages. Tlhe cylinders are geared together so as to revolve at thesame speed in opposite directions.

The paper drawn through or between the cylinder D, D lays upon aninclined plane of the bag and allow av or table J, on the upper part ofthe framing,

near the opposite end to the reel 0, and as soon as the cylinders haveperformed a revolution and delivered the paper for a bag and becomestationary, the three shear arms (Z, c, f, come into operation, d,cutting off the piece from the roll, and e, and f, cutting away part ofone edge so that the remaining part of the same edge can, when the pieceis doubled,be lapped over it to make the joint or seam in the bottom ofthe bag.

The form of the piece after it is cut is shown in red lines in Fig. 6,the lines 1, 2 showing the form of the piece cut out by e, and f. Toshow the form more distinctly the Fig. 8, is given, the dotted linesshowing the part out out. The shear d, hangs on a pin 3, and cuts on theedge of a bar 9, in front of the feed rollers (see Fig. 3, and dottedlines in Fig. 6) e, hangs on a pin 4, and cuts on the side edge h, ofthe lower part of the inclined plane J ,1 which is made na rower thanthe upper part, and hangs on a pin 5, and cuts on the edge of a strip ofsteel 2', standing out at a right angle to the edge 71, meet-ing thesaid edge h, where the point of the shear e, meets it in cutting. Theedge 9', and the edge 71, are steeled and the shears (Z, 6, f, may besteel bars, or wooden or iron bars having a strip of steel secured tothem. The shears are caused to descend and make their cuts by means of acam K, on the driving shaft B, which, once during every revolution ofthe shaft comes into operation under and raises a short lever L, hung ona fulcrum j, in the sidev of the framing; this lever L, is connected bya strap or link is, to one arm of a long lever M, which hangs on afulcrum Z, in the framing, the other arm of the said lever connecting bya rod m, with another lever I on a fulcrum a, and the said lever Iconnect-ing by a rod 0, with the shear (Z, the lever M, is connectedalso by a rod 79, to the shear e; by the action of the cam K, on thelever L, the shear (I, and e, are brought down past the edges g, and 7a,and as e, descends its end (being suitably formed for the purpose)presses on the end of j', and forces it down past the edge of z,

thus, it will be seen that all the shears operate' at the same time:they are all raised by springs attached to each, after the projection ofthe cam K, which operates on the lever L, has passed the lever andceased to operate upon it.

The piece of paper is now supposed to be cut out in the proper form forthe bags; the next operation is that of folding it, by referring toFigs. 3, and 6, it will be seen that there is a narrow slot (7,extending across the inclined plane J, dividing it into twoparts, inline with the. point where the shears 6 and f, meet, above the inclinedplane there is a frame 0, which vibrates on a shaft P, and which carriesat its upper end a blade r,

.having a blunt edge which is caused. by the the blade 1", which I willterm the folding creaser, creases the sheet and folds it as it drives itthrough the slot, rising as soon it has driven the fold through. Thefold is seized between a pair of cylinders s, s, .which revolvecontinuously and the folded sheet passes between them (see dotted linesin Fig. 3) and is deposited by them upon a flier Q. The folding .creaseris caused to descend after the cutting off and cutting out of the sheet,by means of a strap a, passing over a pulley t, on the shaft P, the saidstrap being secured to the periphery of the pulley,

and one of its ends being connected to a spring R, secured to the sideof the framing, the other end being connected to the upper end of alever S, which hangs on a fulcrum o, in the framing. The lower end ofthe said lever S, is moved once during every revolution of the drivingshaft B, by a projection 6, on the cam T, on the said shaft, whichcauses the upper end to pull on the strap '20, and turn the pulley inthe proper direction to bring down the creaser which is caused to ascendagain as soon as the pro jection 6, passes the lever S, by means of thespring It, which pulls back the strap. The lever S, whenthe cam is notin operation on it, rests against a pin 7, in the side of the framing.The cylinders S, S, receive their revolution through the endless chainG, which passes over a chain wheel 10, on the axes in of S, thecylinders being geared together by spur wheels.

The flier Q, is a light frame of suflicient size for the sheet tolayupon, it is unnecessary to describe its construction as it might be madein different ways. It is sufficient to say that it rocks upon a shaft y,which rests in bearings in the sides of the framing. IV hen it is atrest it occupies an inclined position as shown in Figs. 1, 2, 3, and itis in this position when the paperis deposited upon it by the cylinderss, s. As soon as it receives the paper it turns over and deposits itupon the endless apron U, which.runs around two rollers. V, and

IV and instantly resumes its former pos1- tion. The movement of theflier is effected by means of a strap 2, which passes around and issecured to a pulley 8, on one end of its shaft y, (see Fig. 2,) the endsof this strap are connected to two levers 9, and 10, which are operatedupon by a cam X, on the driving shaft once during every revolution; itis turned over by the cam acting on the lever 9, and returned to itsstationary position by the cam acting on 10, immediately after. In thedrawing it is supposed to be just raised ready to receive the paper, thecam just ceasing to operate upon 10.

The endless apron U, carries the paper to the pasting and lappingapparatus; the bottom of the bag being first pasted and lapped and theside being afterward pasted and lapped. The bottom pasting apparatus isat the side, and the side pasting apparatus at the end of the machine.The operation of that which pastes the side will I think be most readilyunderstood, I will describe that first, although it does not come intooperation till after the others; before doing this I will howeverexplain the carrying apparatus. I

As the apron U, carries the paper along fixed position for lapping andpasting. The aprons receive motion both together at proper intervals bymeans of an oval cog wheel 11, on the axis of the roller V, which gearsinto a toothed wheel 12, on the driving shaft. The wheel 12, is in theform of an ellipse with a segment cut off, the part forming the chord ofthe segment having no teeth, so that while that is passing the wheel 11,it does not give motion to it. The two cog wheels are so arranged thatthey give motion to the roller V, at the proper time to move the apron,the said roller W', being geared with the roller Z, causes the twoaprons to move together. In the drawings the aprons are supposed to beat rest with a piece presented to each pasting and lapping apparatus.

The side pastingand lapping apparatus shown in Figs. 3, and 5, consistsof the paster, creaser, lapper, paste feeder and paste trough. Thepaster consists of a brush 13, or piece of leather attached to a stripof wood of sufiicient length to paste the whole length, of the lap atonce, attached by two arms 14, to the main shaft B; it revolves and onceduring every revolution comes into contact with the paste feeder 15, andis supplied with paste. The feeder consists of a bar attached by arms toa shaft 16, which is parallel with the shaft B, and is driven by an ovaltoothed wheel 17, gearing into the wheel 12, on B; it is caused to revole through the paste in the trough 18, and collect sufficient paste tosupply the paster as they pass each other revolving in oppositedirections. The lapper consists of a bar of wood or metal 19, which ishinged to a stationary bar 21, running across the framing and must be atleast as long as the bag; it lays flush with the upper part of the saidbar 21, as shown in Fig. 3, and is stationary except while it makes thelap when it folds over on to the top of 21, as shown in Fig. 5. Thepaper is deposited by the aprons with the part forming the lap on thetop of the lapper as shown in Fig. 3, and while it is in this positionthe paster in-passing pastes it; and immediately after this the creaserwhich consists of a long blade 22, attached by arms 23, to a vibratingshaft 24, comes down upon the line where the lap ping commences, whichis close to the edge of the upper side of the bag, and holds it whilethe lapper turns over. The creaser is however withdrawn in time toescape the lapper, which turns the pasted lap over the edge of the upperpart of the bag and then turns back again to allow the bag to be thrownout of the machine by the following movement of the aprons. The creaseris operated by means of a long lever 25, attached to one end of itsshaft (see Fig. 5,) which is depressed by a rod 26, attached to one endof another lever 27, hung above it on a fulcrum in the side of theframing, the opposite end of the said lever 27, being raised by a stud28, on the shaft B, once during every revolution of the shaft.

The creaser is raised when the stud 28, has passed the lever 27, by aspring 29, attached to the lever 25, and to the side of the frame. Thelapper is turned over to make the lap through the agency of the samestud 28, which actuates the creaser, the said stud raising one end of alever 31, hung on a fulcrum on the side of the framing, the opposite endof the said lever 31, being con nected by a link 32, with the shorterarm of a lever 33, which also works on a fulcrum secured in the side ofthe framing, the longer arm of the said lever 33, having a strapattached which passes around a semicircular tumbler 34, attached to thelap-per, and which by being raised turns over the lapper, which isreturned down or back again after the stud passes the lever 31, by aspring 35, which is placed under the stationary bar 21, and connected tothe lapper by a cord or strap. The paster 13, instead of being securedimmovably to the shaft B, is movable; the arms 14, being allowed toslide through holes in the shaft, and having nuts on their back ends toprevent their drawing out. Springs 36, (see Fig. 7,) are placed betweenthe shaft and paster to keep it out from the shaft. This arrangement isfor the purpose of allowing the brush to be drawn toward the shaft atcertain parts of its revolution to prevent pasting the apron and to makeit clear the edge of the paste trough; the drawing in being effected byeccentric ways 37, which are stationary on the framing, and inside whichthe ends of the paster pass as it revolves.

To return to the bottom pasting and lapping apparatus at the side of themachineI will first remark that it is essentially the same as that whichlaps and pastes the side of the bag, but its position requires it to beoperated by different means, which will be best understood by referringto Fig. 4. The lapper 38, is similar to the other one, and is hinged tothe side of a stationary table 58,

which is immediately under the two aprons, and under the rollers Z, Z,to this .point one bag is brought every time the aprons becomestationary and the pasting and lapping apparatuses come into operation.The edge of the apron is just over the hinge or joint of the lapper andthat part of the bottom side of the folded paper which forms the lapoverhangs the edge of the apron. The apron Y, is narrower than that U,to make room for the bottom pasting apparatus. The paster 39, which isplaced parallel with the movement of the apron, is attached to a shaft40, in a similar manner to the other; this shaft 40, has a constantrevolution which it receives through spur gearing from a counter shaft41, (see Fig. 1,) which is driven by bevel gearing from the main drivingshaft B. The paste feeder 60, is attached to the shaft 42, which isdriven by part of the same train of gearing and feeds the paster fromthe trough 43. The paster is drawn toward the shaft during itsrevolution to make it clear the apron and trough, by eccentric ways 59,on the framing. The creaser 44, is hung on a vibrating shaft 45, and isdepressed by a stud 46, on the paster shaft 40, which actuates a lever47, on the creaser shaft. It is raised by a spring 52, attached to theframing. The lapper 38, is turned over to make the lap by a strap 48,which passes around a semicircular tumbler 49, on the end of the lapper.The other end of the said strap passes partly around and is attached toa tumbler 50, which fits loosely upon one end of the feeder shaft 42.This tumber 50, is in the form of a circle with a projection 51, standing out from a part of its periphery. On the face of the tumbler thereis a stud 53, upon which rests the end of a lever 54, which. hangs on. apin 56, secured in the framing. This lever has two arms which are nearlyside by side, the one resting on the stud, and the other arm which isbent slightly downward from it, being operated upon by a tappet 55, onthe feeder shaft 42. This tappet at the proper time for turning over thelapper, presses down the lever 54, which pressing on the stud 53, causesthe tumbler to turn a short distance and by pulling on the strap 48, toraise and turn over the lapper to fold over the lap.

The tappet 55, is of such length that as soon as the lapper is turnedover and the lap made it passes the lever 44, and leaves the lapper freeto be pulled down again by a strap which is attached to a spring 57,below the table 58, the return of the lapper pulling on the strap 48,draws back the tumbler 50. The projection 51, on the periphery of thetumbler is for the purpose of pulling on the strap 48, in a directionmore favorable to the turning over of the lapper.

The machine turns out one finished bag at every revolution of the mainshaft, but there are four bags always in it under different stages ofthe manufacture. At the time one is being cut out, a second is beingplaced upon the apron, a third is pasted at the end, and a fourth at theside; each succeeding revolution of the machine finishing and throwingout one bag, commencing one and bringing three others to a more advancedstage of the operation. The machine may be driven at the rate of thirtyrevolutions aminute which would make eighteen hundred bags per hour.

The width of the bags may be varied by changing the cylinders D, D, andby moving the inclined plane J, so as to bring the slot 9, nearer to thecylinders D, D. The shears and folding creaser may be allmovable withthe inclined plane so that their correct operation may be alwaysinsured.

The machine is susceptible of various changes in the arrangement of theparts; for instance, the folding apparatus and shears for cutting outthe piece to leave the bottom lap may be placed at right angles to theirpresent position and the width of the bags may be regulated by the widthof the paper, and the depth by the quantity given out by the cylinder.

What I claim as my invention and desire to secure by Letters Patent, is

1. Giving the proper form to the piece of paper or material from whichthe be is to be made, by means of the shears e, and f, which cut on theedges of or on edges attached to the stationary table or inclined planeJ, on which the paper is delivered, and cut out a rectangular piece, asshown in Figs. 6, and 8, from that part which is to form one side of thebag, so as to leave a lapping piece on the part which is to form theother side of the bag, as herein substantially set forth.

2. The pasters 13, and 39, in combination substantially as describedwith the feeders 15, and. 60, which revolve or pass through the pasteand supply them with a proper quantity for pasting each lap.

3. The combination of the creasers 22, and 44, and the lappers 19, and38, with the intermittingly moving feed rollers W, Z, and aprons U, Y,in the manner substantially as described the said creasers and lappersbeing brought successively into operation on the bags during theintermissions in the motion of the feed rollers as set forth.
